摘　　要：利用反相共沉淀法,合成了掺杂过渡金属铁的C eO2纳米颗粒。通过X射线衍射(XRD)、透射电镜(TEM)、傅里叶变换红外(FT IR)光谱、紫外-可见(UV-V is)光谱等测试手段对产物进行了分析和表征。结果表明,掺杂铁的C eO2纳米颗粒是纯立方莹石结构;过渡金属铁掺入了C eO2的晶格;其相比于不掺铁的C eO2纳米颗粒吸收峰发生轻微红移。Fe-doped CeO2 nanoparticles were prepared by reverse coprecipitation.The product was characterized and analyzed by X-ray diffraction,transmission electron microscopy,Fourier transformation infrared spectroscopy and ultraviolet-visible spectrometry.The Fe-doped CeO2 nanoparticles were pure cubic fluodte struture,and transition metal Fe was doped into CeO2 crystal lattice.Compared to Fe-undoped CeO2,the absorption peak of Fe-doped CeO2 nanoparticles had a slight red shift.
